Miniature brushless motors available with choice of options

Rotalink continues to expand its DC motor schedule with a new line of miniature brushless motors for nominal output torques to over 250 mNm at maximum efficiency and maximum power ratings to 270 W. The new BL brushless motors are very competitively priced and together with Rotalink's own innovative and uniquely designed precision gearboxes, motor feedback devices and motion controls, offer excellent price vs. performance for complete miniature power transmission solutions.

The BL motor range is available in both 12 and 24 VDC versions, complete with three phase hall effect commutation for smooth and precise speed and/or position control. The highly efficient brushless design has an inherently low electrical noise factor and unlike brushed DC motors is not prone to commutation sparking; so the motor is ideally suited to EMC sensitive and safe environment use. In addition, the non contacting characteristics will suit applications where long life and high reliability are of prime concern. The BL range includes five frame sizes with nominal diameters of 29mm, 32mm, 45mm, 57mm and 65mm.

The new BL brushless motors are particularly well matched for use with the brushless version of Rotalink's recently launched drag-and-drop/flow chart programmed Red Drive motor driver and controller which has significantly reduced the entry costs for high performance yet easy-to-use brushless servo control. The BLDC Red Drive has a 10A current rating and is complete with hall sensor inputs for brushless commutation, incremental encoder feedback inputs plus 27 programmable TTL level I/O pins for analogue and digital machine interfacing.

Full details of the new BL range and the brushless Red Drive are covered in Rotalink's new 80 page miniature power transmission and motion control products catalogue. The catalogue and Rotalink's website at www.rotalink.com also features in depth coverage of the complete range of spur and planetary styles gearboxes with built-in flexibility to allow users to match their budget and performance requirements by selecting standard or enhanced polymer gears with a choice of sintered or ball bearings. Rotalink's unique ovoid style gearboxes feature combined spur and ultra-polymer planetary stages in very compact designs for extremely high torque-to-size ratio geared solutions.

Other products include novel incremental and absolute encoder feedback devices that may be assembled directly on the front motor shaft or rear gearbox shaft in space saving designs that help to complete highly integrated mechanical solutions for miniature power transmission.
